Using the GPX utility and the Chart Work family of programs is it possible to do on an electronic nautical chart the work you do in a traditional way. \\ The three programs are:

  - Lines of position and Great Circle sailings (orthodromic).
  - Piloting: Currents and coastal fix.
  - Search & Rescue search patterns.
GPX output includes:

__Coastal navigation LoP__

  * Bearing
  * Range
  * Horizontal angle
__Celestial navigation LoP__
  * Marcq St. Hilaire Line of Position
  * Circle of Position
__Radionavigation LoP__
  * RDF bearing
__Route__
  * Great Circle
  * Composite
__Piloting and coastal fix__
  * Currents Drift and Set
  * Lasheras
  * Ciclonic method
  * Fix by simultaneous Distance and Bearing of same object. Geographic Range, D( waterline, top of object )
  * Fix by 2 simultaneous Horizontal Angles
__SAR search patterns – Patrones de búsqueda SAR__
  * Expanding Square
